The Pyramid acetabular system allows for excellent primary stability without excessive seating forces due to the unique unidirectional macrostructure surface. The metal shell is made of a Ti6Al4V alloy and has a constant press fit ratio between reaming and oversize for all diameters and is flattened in the pole –region.
There are 2 coated cups with exactly the same properties available. For the dual phase coating there is a 200μm Ti-VPS + 20μm CaP (calcium phosphate) layer. For the single phase coating there is only a 20μm CaP (calcium phosphate) layer.
The threaded hole in the pole is sealed by a screw after implantation.
Cups and inlays have been designed for a maximum Range of Motion. This results in possible large head sizes for the following cups:
(valid for both cross linked PE and ceramic inserts)
